I am attempting to add new subscribers to tags, but the tags are not updating with the newly added individuals. I received an error message, stating that Convertkit's "servers were not able to be reached" about 3 hours ago. I attempted to add them again, just a few moments ago and still my tags will not update. I did not receive an error message this time, just the normal green message across the top saying that I would receive an email when the subscribers were added. Is this an ongoing issue and is there an estimated time when this will be resolved?
